How Change Happens bridges the gap between academia and practice, bringing together the best research from a range of academic disciplines and the evolving practical understanding of activists to explore the topic of social and political change. The world committed to global transformative change in 2015, with the 2030 Agenda and targets in the Paris Climate Agreement to stay well below 2°C and achieve carbon neutrality by the second half of the century. We need to understand how change happens in order to accelerate our pathway to a safe future. Duncan Green's book is a timely and badly needed guide to bringing about the necessary social and political change.
